    - Register Window Message Hi All, Here it is what I want to do . I have a Windows Form application (app1) which at a certain moment sends a registered windows message to other Windows Form application (app2) which only listen for this window message. When app2 catches the message it performs some task and then wait again for the message. All fine by now. Because the app2 does not expose any interaction with the user (the main window of app2 is minimized to sys tray) I'd like to have the app running as a .NET Windows service. Is it possible somehow to have a Windows service application listening to a registered window message? Thanks, Mircea Tag: SizeGripStyle.Auto behaviour Tag: 94352

    - Reflection question : finding the exposed properties of a Control Given a generic Control object, how can I iterate through all the properties exposed by the control ? Different classes of control expose different properties. Ideally I'd like to find all the properties that are exposed within the "Appearance" and "Layout" categories of the form designer's property grid. I imagine I can do this via reflection but I don't really know where to start. Any pointers ? Tag: SizeGripStyle.Auto behaviour Tag: 94351

    - Transforming mouse coordinates Hi Thanks for taking the time to check this post. Any help/suggestions are appreciated. I have an owner drawn (GDI+) document generation application that is made up of embedded objects. The document acts simply as a layout container and delegates painting to the embedded items. The document supports scaling and rotation of these items. This is handled using transformations to hide to implementation of this functionality from the embedded items. The problem I am struggling to resolve is that some of the embedded items give user feedback based on the position of the cursor (this is passed to the paint method of the items). If the item has been rotated, it still stores any internal hotspot coordinates in the none rotated form and the cursor position no longer matches (it has no knowledge of the transformation). ie ... the cursor triggers the hotspot feedback when it is placed on the document in the place the hotspot would be without any rotation. Is there a simple way to transpose the coordinates. I have the angle of rotation, the origin and the start point .... I need the mouse position relative to the item as if it had not been rotated. Any ideas. Ideally, I would prefer not to have to do the maths the old fashioned way, as I would like to support more transformations at a later time. Thanks for leaving your thoughts.

    - datagrid edit not saved on exit I have a bound datagrid on a form, with a close button. All the close button does is call me.close. If I edit a cell, then click my close button, the edit can be seen in the grid, as expected, when I enter my form_closing event code. However if I edit a cell then click the "X" in the top right corner of the form, the form_closing event fires, but the grid shows the "old" value of the cell, thus the change to the cell is not saved. I am working around this currently by preventing the user form using the "X" to close the form, but there must be a better way ? Tag: SizeGripStyle.Auto behaviour Tag: 94344

    - ActiveX ruins Validation events. Hi. I am using an ActiveX control in a .NET application which I put on a form. I have another .NET control on that form that handles the Validating event. The method that handles the Validating event, shows a message box and sets e.Cancel = True. When I click any other control in the form, the message box shows and the focus returns to the control that handled the Validating event. The problem happens when I click on the ActiveX control. The ActiveX control gets the focus and the focus doesn't return to the validated control and no message box is displayed. With a different ActiveX control the message was displayed, but the focus didn't return to the validated control. I reproduced the bug in a small application. In that application I wrote an ActiveX in VB 6 that has an edit box. In a c# .NET application I put on a form the ActiveX and 2 text boxes. One text box is validated and is called textBoxValidated and the other one is not vaildated and is called textBoxRegular (the regular text box is used to demonstrate regular validating behaviour) . In this form, the first time you click on the ActiveX, it works ok, but the 2nd time it doens't work ok Here is the code of the form: " using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; namespace WindowsApplication5 { /// <summary> /// Summary description for Form1. /// </summary> public class Form1 : System.Windows.Forms.Form { private AxProject1.AxUserControl1 axUserControl11; private System.Windows.Forms.TextBox textBoxValidated; private System.Windows.Forms.TextBox textBoxRegular; /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.Container components = null; public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); // // TODO: Add any constructor code after InitializeComponent call // } /// <summary> /// Clean up any resources being used. /// </summary> protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(Form1)); this.textBoxValidated = new System.Windows.Forms.TextBox(); this.axUserControl11 = new AxProject1.AxUserControl1(); this.textBoxRegular = new System.Windows.Forms.TextBox(); ((System.ComponentModel.ISupportInitialize)(this.axUserControl11)).BeginIniÂt(); this.SuspendLayout(); // // textBoxValidated // this.textBoxValidated.Location = new System.Drawing.Point(448, 72); this.textBoxValidated.Name = "textBoxValidated"; this.textBoxValidated.TabIndex = 2; this.textBoxValidated.Text = "validated text box"; this.textBoxValidated.Validating += new System.ComponentModel.CancelEventHandler(this.textBox1_Validating); // // axUserControl11 // this.axUserControl11.Enabled = true; this.axUserControl11.Location = new System.Drawing.Point(128, 160); this.axUserControl11.Name = "axUserControl11"; this.axUserControl11.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axUserControl11.OÂcxState"))); this.axUserControl11.Size = new System.Drawing.Size(320, 240); this.axUserControl11.TabIndex = 3; // // textBoxRegular // this.textBoxRegular.Location = new System.Drawing.Point(544, 152); this.textBoxRegular.Name = "textBoxRegular"; this.textBoxRegular.Size = new System.Drawing.Size(88, 20); this.textBoxRegular.TabIndex = 4; this.textBoxRegular.Text = "Regular text box"; // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(824, 470); this.Controls.Add(this.textBoxRegular); this.Controls.Add(this.axUserControl11); this.Controls.Add(this.textBoxValidated); this.Name = "Form1"; this.Text = "Form1"; ((System.ComponentModel.ISupportInitialize)(this.axUserControl11)).EndInit(Â); this.ResumeLayout(false); } #endregion /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.Run(new Form1()); } private void textBox1_Validating(object sender, System.ComponentModel.CancelEventArgs e) { MessageBox.Show("DAN:("); e.Cancel=true; } private void button1_Click(object sender, System.EventArgs e) { Application.Exit(); } } } " Does any one know how to overcome this bug?

    - Get XML using NetworkCredential Hi, I'm developing a windows application in C# which gets a xml string from another website. To get the xml I'm using the following lines of code. <cut> XmlUrlResolver resolver = new XmlUrlResolver(); NetworkCredential myCred = new NetworkCredential("myusername", "mypassword", "http://del.icio.us/api/tags/get?"); CredentialCache myCache = new CredentialCache(); myCache.Add(new Uri("http://del.icio.us/api/tags/get?"), "Basic", myCred); //resolver.Credentials = CredentialCache.DefaultCredentials; resolver.Credentials = myCache; XmlTextReader rdr = new XmlTextReader("http://del.icio.us/api/tags/get?"); rdr.XmlResolver = resolver; // Set the resolver. </cut> The code works fine, but when I try to get the xml I receive an error: "authorization required". This is because the visual studio application identifies itself other than a normal browser. Is it possible to set the user agent for my program?

    - problem in context menu Hi, I'm using a context menu on a treeview control in VS 2003. The problem happens when displying the context menu for the first time, the tree node for which to display the context menu needs to be right clicked twice (not a double click but two distinct right clicks). After the first time a single right click is enough for any tree node. Any ideas how to fix it? Another problem, when right clicking a tree node that is not in focus the context menu won't open. It first must be in focus by left clicking it. How can I force it to open? (like the behavior of windows explorer). Thanks in advance, Ohad Tag: SizeGripStyle.Auto behaviour Tag: 94334

    - Create custom cursors in vs2005 Hello, I've tried to find something on this in the newsgroups but came up with nada: I'm trying to create a custom cursor in VS2005. I have a .cur file that I have put in my "Resources" folder. The resource manager does not recognize the .cur extension and puts it under the generic "Files" category (vs. "Images", "Icons", "Strings", etc.) When I try to refer to the cursor, like: Properties.Resources.arrowTrans, apparently it comes out to a byte[]. How can I convert this into a Cursor object? I used to have code in 2003 that used the GetManifestResourceStream method, but that doesn't work. And how does the "BaseApplicationManifest" option work in the "Build Action" item (vs. "None", "Embedded Resource", "Compile", and "Content") in the file Properties window?

    - URGENT: VS2005 Text Rendering Issue First up, sorry for cross-posting. I have what is (to me, at least, an urgent issue) with the look/feel of my applications. I have been using VC# EE Beta2 until about a week ago and I have just bought VS2005 Professional RTM. All programs I've written in VC# EE now do not render text correctly. The labels and controls render much the same way as they do with .NET1.X, ugly and about 1.5 spaced. New projects look fine, like a native Windows program and don't suffer the rendering issue. For my upgraded VC B2 apps I've made sure that UseCompatibleTextRenderer = false and I've done a clean build. Can some one *please* help me with this problem. Thanks in advance, Annette.

    - Application window gets smaller than MinimumSize Hello, I am writing an application in Visual Studio .NET, C#. Application is set to maximize after start. I set in Form properties MinimumSize to 800; 600. Everything is OK - I can't resize application window to be smaller than 800 x 600. But, when I set screen resolution to 800 x 600, set task bar to be always visible (and also has height of a few heights of standard task bar height - that working area of the desktop is maybe 800 x 500), application window is smaller than 800 x 600 (which was set as minimum). Application window fit working area of screen (screen size minus area of always visible task bar) which is smaller than minimum size set in Form properties. When I click on Maximize Box, application window gets bigger and fits all the screen size (some area of my application's window is then under task bar) -- it is what I want. I tried to manually set form Height to 600 on Resize event, but it did not help. How to cause that application window is always not smaller than 800 x 600 ?

    - CCeDocListDocTemplate on Windows Mobile 5.0 Problems Hello all, I am currently using the CCeDocListDocTemplate class, however, I'm having problems with it on a Dell Axim 51, which uses Windows Mobile 5.0. When the widget is used, it displays the list of files in a mangled format. The format appears to be the first character of the filename followed by the creation date of the file: So for a file named "survey.srv" it would show up as: "s11/12/17". This works fine on the Dell Axim 50, which does not use Mobile 5.0. Are there any known issues with this? Should I be using something else for the Dell Axim 51?

    - Toolstripmenu and -items don't use menu system color setting I've got a customer who has set his menu text to white on black. When using a new VS2005 toolstripmenu (tsm) we run into all sorts of problems, because the tsm doesn't automatically use the menu system backcolor. The menu's all have white text on light grey backgrounds and are totally unreadable. Is this a bug? Seems like it, since they *do* take over the menu text system color as forecolor. I've tried using a small routine to walk over all toolstripmenuitems (and since they're not members of the forms controls that's tedious as well) and set their backcolors, and it works, but now the highlight color and the checkmarks remain stubbornly purple. It looks awful and annoyingly there are no properties available to set those. This way the entire toolstripmenu becomes utterly useless. Has anybody got a clue how to fix this?

    - TabPage Alignment property change at runtime problems/bug Hi! When TabPage.Alignment property is changed at runtime tabs are not displayed correctly i.e. text is not displayed and visual style changes to something not seen with any of the available styles. It has been reported many times by different users. After googling for some time (can I use this word on MS forums?) I found short explanation for a reason. Setting Alignment property causes control to be destroyed and recreated with new handle and setting it with container causes the whole mess. However, I have not found any hints on solution to this problem. Are there any KB articles describing this issue or is there any solution to that problem? Tag: SizeGripStyle.Auto behaviour Tag: 94260

    - Question about IComponentChangeService - OnComponentAdded() I am trying to create a service that will hook to the events fired by the IComponentChangeService. I will use this new service to automatically position controls based on their size and location, the controls have to stay for example within an area of 300, 300. So if anyone created a control outside this area the control will automatically be moved to the new location within the 300, 300 area. When you listen to the event ComponentChanged of the IComponentChangeService you get the components name, the property that changed, the new and the old value of the property. Thus when a user changes the location of a component or the size and its bounds are outside the 300, 300 area I can successfully roll back to the old property value. But now for new components you can hook to the ComponentAdded event but there is one big problem. When this event is fired the component does NOT have the location property set yet. Therefore I am wondering where or when is the Location property actually set? And why doesn't the ComponentChanged event get fired when the location property is set afterwards because that would have also fixed my problem.

Make sense? I basically want to create the concept of client size but within the client area, so a sub-client area.. Tag: SizeGripStyle.Auto behaviour Tag: 94250

    - Use Running App All - I have used mtux to check for a running app and close it down if it a previous app instance is running. Now, when a user double clicks on one of the saved application files, I'd like for the existing instance of the application to come to the front and use the file the user double clicked. I have no issues doing this when no instance of the app is running but if it is already running, how do I go about this? Thanks, Brian Tag: SizeGripStyle.Auto behaviour Tag: 94246

    - How do I simplify this code I have a select case which opens various forms as ShowDialog. Notice the repetition; \\ Case "btnManageJobs" Dim f As New f010Jobs Me.Visible = False f.ShowDialog() Me.Visible = True Case "btnSeqOfOper" Dim f As New f050SqOO Me.Visible = False f.ShowDialog() Me.Visible = True Case "btnViewer" Dim f As New f060View Me.Visible = False f.ShowDialog() Me.Visible = True // How can I take the code... \\ Me.Visible = False f.ShowDialog() Me.Visible = True // ... and put it after the select case block? IOW is there any way to declaire "f" before the select case block and give it the form name within the select case and then run the "f.ShowDialog" after the block. Orrrrr is there a simpler way to do this? thank you, dbuchanan Tag: SizeGripStyle.Auto behaviour Tag: 94244

    - System.Drawing - SafeNativeMethods . GdipFillRectangleI method causes a lot of page faults We just profiled our application and noticed that SafeNativeMethods.GdipFillRectangleI method (called by Graphics.FillRectangle) in System.Drawing causes 88% of all of our -soft- page faults. We are soft faulting on an order of 2000 spfs/sec with 10 charts - with one charts we are to 600 SPFs/sec. Both numbers are high. We are a charting intensive, real-time trading .NET application that plots real time trading data on a high frequency basis. Does anyone know of any performance issues with GDI drawing functions in .NET framework...? Tag: SizeGripStyle.Auto behaviour Tag: 94218

    - DataGridView Update Hi All, I am using VS 2005 and would like to accomplish the following: Assuming I have 3-4 grids on a given Windows Form. I would like to update these grids individually on a specified timer interval without blocking the UI thread. When the info is available for a specific grid, it is updated with the latest values from the SQL Server 2000 database backend. What would be the best way to do this? I think I'd need to start a new thread for each grid's Update/Refresh method or maybe even use the new BackgroundThreadWorker object. Any ideas, hints, code tips (VB.NET). Regards, Giovanni P.

    - Handling the Windows "No Disk" MessageBox I have a Windows application that reads images from a CD or DVD. If the media is removed from the drive and the user selected an image to in the DataGrid, then Windows will display a MessageBox informing the user that no media exists. This MessageBox also prompts the user to Cancel, Retry, or Continue. I don't know anything about this MessageBox except that my application crashes a horrible death if the user selects Cancel or Continue. I would like to be able to handle a Cancel selection if possible. Does anyone know what this MessageBox is that Windows (XP) displays automatically? If so, do you know how to read the DialogResult from it? The crash comes when my application proceeds with trying a call that will absolutely NOT work without the media. Here is my stack trace from the resulting crash: <type>System.ArgumentException</type> <message>The Win32 handle you passed to Icon is invalid or of the wrong type.</message> <caller>.ctor</caller> <stack> at System.Drawing.Icon..ctor(IntPtr handle) at System.Drawing.Icon.FromHandle(IntPtr handle) at DCDLibrary.IconTool.GetLargeIcon(String filename) in C:\Documents and Settings\clfenley\My Documents\Visual Studio Projects\InspectionViewer\DCDImaging\IconTool.vb:line 138 at InspectionViewer.ViewerMain.GetPlans(String resultsId) in C:\Documents and Settings\clfenley\My Documents\Visual Studio Projects\InspectionViewer\InspectionViewer\ViewerMain.vb:line 864 at InspectionViewer.ViewerMain.GetImages(String resultsId) in C:\Documents and Settings\clfenley\My Documents\Visual Studio Projects\InspectionViewer\InspectionViewer\ViewerMain.vb:line 758 at InspectionViewer.ViewerMain.ShowDetailsObjects(String resultsId) in C:\Documents and Settings\clfenley\My Documents\Visual Studio Projects\InspectionViewer\InspectionViewer\ViewerMain.vb:line 1161 at InspectionViewer.ViewerMain.DataGrid_CurrentCellChanged(Object sender, EventArgs e) in C:\Documents and Settings\clfenley\My Documents\Visual Studio Projects\InspectionViewer\InspectionViewer\ViewerMain.vb:line 464 at System.Windows.Forms.DataGrid.OnCurrentCellChanged(EventArgs e) at System.Windows.Forms.DataGrid.set_CurrentCell(DataGridCell value) at System.Windows.Forms.DataGrid.OnMouseDown(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at InspectionViewer.AppState.Main() in C:\Documents and Settings\clfenley\My Documents\Visual Studio Projects\InspectionViewer\InspectionViewer\AppState.vb:line 86</stack> Regards, Carl Tag: SizeGripStyle.Auto behaviour Tag: 94207

    - Transparent label flicker when drawn on form I am having troubles with forms that have a large number of labels with transparent backgrounds causing a good deal of flicker while originally drawing the form. I have created a new label class which inherits from Label and has UserPaint and DoubleBuffer set in the control styles, and this makes no difference. In 2.0, I set double buffering on the form and this also made no difference. Anyone have any suggestions on how to deal with this? A form with 100 transparent background labels should not flicker the way it does on my PC (Athlon 64 3500, 512MB) - you can see each label being drawn individually. I have tried my test case on numerous computers and the same thing happens on each. Thanks, Bob Dankert Tag: SizeGripStyle.Auto behaviour Tag: 94206

    - RadioCheck Menu options Hi, I have an application (written in c#) where I am using a context menu for some custom objects on the screen. The context menu has a sub-menu which consists of 4 options, on which I have set the RadioCheck option to true, as I want these items to function as a group of radio buttons. Since I couldn't find any option to set which group each of the items was in I assumed it would work as it is. However, when I test it, selected an item on the menu does not de-select the one that is currently selected. Surely I don't have to do that myself do I? Have I missed something? Do I mis-understand something, or is there some basic functionality missing? Thankyou. Paul Tag: SizeGripStyle.Auto behaviour Tag: 94202

    - Another CreateObject C# question My question is how can I in C# call methods on a COM object without having an interface or a RCW referenced. I have a COM component that I cannot import into .NET, it throws a bunch of errors. In VB.NET I was able to do the following: Dim instance As Object impromtuApplication = CreateObject("Impromptu.Application") impromtuApplication.DoSomething("Paramters") In C# I have somewhat the equivelant code: string progId = "CognosImpromptu.Application"; Type comType = Type.GetTypeFromProgID(progId, true); appInstance = Activator.CreateInstance(comType); appInstance.DoSomething("Paramters"); // this line fails because it says no method like this exists So I know I have to cast this object to an Interface or COM object, is there anyway to do this WITHOUT having the RCW or Interface. I don't want to start writing VB.NET code to get this to work <shivers> Thanks in advance Tag: SizeGripStyle.Auto behaviour Tag: 94198

Can someone explain the behaviour of SizeGripStyle.Auto which is a
value for the Form.SizeGripStyle property? According to the MSDN doc it
just says
"The sizing grip is automatically displayed when needed." What are
those "When needed?" situations.
In the doc for Form.SizeGripStyle it says "You can set this property to
display the sizing grip or have it automatically displayed based on the
setting of the FormBorderStyle property"
But setting the FormBorderStyle property to either Sizable or
SizableToolWindow doesnt bring up the SizeGrip on the form.
How is the FormBorderStyle related to the SizeGripStyle.Auto property.?
